Resumen

CORNWELL, EDWARD. A NEW PROCEDURE FOR THE CHEMICAL CONNECTIVITY INDEX APPLICATION. J. Chil. Chem. Soc. [online]. 2004, vol.49, n.4, pp.351-354. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072004000400015.

Multiplicative numerical factors (Fc) were calculated to modificated each term (di * dj)-0.5 of 1c v index. The Fc factors were calculated using: nine linear equations system based on the experimental boiling points (B.points,exper.) of nine saturated hydrocarbons, the type of the molecular two-carbon fragment and the number of hydrogen atoms attached to them, that evaluate the chemical graph vertex of the molecule . It was shown for a group of fifty saturated hydrocarbons that smaller differences were obtained between experimental boiling points (B.points,exper.) and those calculated by each (di * dj)-0.5 * Fc contribution to 1cv index , than the differences between boiling points (B.points,exper ) and those calculated by means of the linear correlation f: (B.points,exper. ) Æ 1c
